FIELD OF THE INVENTION

The present invention relates to electrical connectors, and moreparticularly, this invention relates to orthogonal card to circuit boardelectrical connectors.

BACKGROUND

Conventional card edge connection layouts may include condensed verticalbackplane connections. Vertical backplane connection layouts may beperpendicular to the airflow through the card environment, e.g., such asa high performance card in a computer, etc., which may be disruptive tonormal functionality e.g. due to overheating, etc. These conventionalcard environments may further lack hot swap accessibility due tocondensed layout designs of vertical backplane connections. Again thismay prove disruptive to normal functionality due to complicationsinvolved in swapping out the vertical backplane components e.g. swappingdue to a non-functional component, swapping due to increasedfunctionality demands, etc.

Embodiments described herein establish advantageous orthogonal card edgeconnection layouts while maintaining a condensed and temperaturebalanced card environment.

In use, the gateway 101 serves as an entrance point from the remotenetworks 102 to the proximate network 108. As such, the gateway 101 mayfunction as a router, which is capable of directing a given packet ofdata that arrives at the gateway 101, and a switch, which furnishes theactual path in and out of the gateway 101 for a given packet.

Further included is at least one data server 114 coupled to theproximate network 108, and which is accessible from the remote networks102 via the gateway 101. It should be noted that the data server(s) 114may include any type of computing device/groupware. Coupled to each dataserver 114 is a plurality of user devices 116.

In more approaches, one or more networks 104, 106, 108, may represent acluster of systems commonly referred to as a “cloud.” In cloudcomputing, shared resources, such as processing power, peripherals,software, data processing and/or storage, servers, etc., are provided toany system in the cloud, preferably in an on-demand relationship,thereby allowing access and distribution of services across manycomputing systems. Cloud computing typically involves an Internet orother high speed connection (e.g., 4G LTE, fiber optic, etc.) betweenthe systems operating in the cloud, but other techniques of connectingthe systems may also be used.

FIG. 2 shows a representative hardware environment associated with auser device 116 and/or server 114 of FIG. 1, in accordance with oneembodiment. Such figure illustrates a typical hardware configuration ofa workstation having a central processing unit 210, such as amicroprocessor, and a number of other units interconnected via a systembus 212.

The workstation shown in FIG. 2 includes a Random Access Memory (RAM)214, Read Only Memory (ROM) 216, an I/O adapter 218 for connectingperipheral devices such as disk storage units 220 to the bus 212, a userinterface adapter 222 for connecting a keyboard 224, a mouse 226, aspeaker 228, a microphone 232, and/or other user interface devices suchas a touch screen and a digital camera (not shown) to the bus 212,communication adapter 234 for connecting the workstation to acommunication network 235 (e.g., a data processing network) and adisplay adapter 236 for connecting the bus 212 to a display device 238.

The workstation may have resident thereon an operating system such asthe Microsoft WINDOWS Operating System (OS), a MAC OS, a UNIX OS, etc.It will be appreciated that a preferred embodiment may also beimplemented on platforms and operating systems other than thosementioned. A preferred embodiment may be written using JAVA, XML, C,and/or C++ language, or other programming languages, along with anobject oriented programming methodology. Object oriented programming(OOP), which has become increasingly used to develop complexapplications, may be used.

Card edge connector environments may become overcrowded due to the highdensity layouts of circuit boards to which the card edge connectors arecoupled. This overcrowding may lead to overheating of the card edgeconnector environments, and furthermore, a lack of ease e.g. in terms ofinsertion angles, in terms of ease of accessibly, etc., when hotswapping cards in the card edge connectors. Embodiments described hereininclude orthogonal card edge connection layouts for maintaining acondensed and temperature-balanced card environment.

FIGS. 3A-3D depicts a connector 300 in accordance with one embodiment.As an option, the present connector 300 may be implemented inconjunction with features from any other embodiment listed herein, suchas those described with reference to the other FIGS. Of course, however,such connector 300 and others presented herein may be used in variousapplications and/or in permutations which may or may not be specificallydescribed in the illustrative embodiments listed herein. Further, theconnector 300 presented herein may be used in any desired environment.

Various embodiments may include one or a plurality of connectors 300.Each connector 300 has a first end 314 having a plurality of firstcontacts 304 configured for coupling with a circuit board (embodimentswith a circuit board shown in later FIGS.). The first contacts 304 maybe copper and/or a conductive contact material of a type known in theart.

Each connector 300 additionally has a second end 316 oriented aboutorthogonal to the first end 314. The second end 316 may have a pluralityof second contacts 308 configured for coupling directly with a card edgeof an electronic device (embodiments with electronic devices shown inlater FIGS.). Similar to the first contacts 304, the second contacts 308may be copper, gold and/or a conductive contact material of a type knownin the art.

Connector 300 also includes a plurality of leads (not shown) connectingthe first contacts 304 to the second contacts 308. The leads connectingthe first contacts 304 to the second contacts 308 may be copper, gold,aluminum, and/or a conductive contact material of a type known in theart. According to various embodiments, portions of all of the leads mayextend along a common plane in connector 300, e.g., along a printedcircuit board. Ensuring that the leads of connector 300 extend along acommon plane may ensure that connector 300 remains spatially compacte.g. to increase component density, etc.

According to other embodiments, portions of some leads may extend alonga common plane in connector 300, while portions of some of the leads mayextend along uncommon planes in connector 300. According to yet otherembodiments, portions of all of the leads may extend along uncommonplanes in connector 300.

Connector 300 may further include at least one ground plane (not shown)extending generally parallel to the leads. The number of ground planesincluded in each connector 300 may vary depending on the preferredembodiment. Each of the one or more ground pins of the ground planes maybe of a same and/or different design, e.g., shape, orientationtherewith, etc., as the first contacts 304. Designing one or more groundpins of the ground planes to be substantially similar to the design ofthe first contacts 304 may advantageously ensure a spatially compactconnector 300.

It should be noted that the plurality of leads connecting the firstcontacts 304 to the second contacts 308 are not readily visible in FIG.3A because they reside on an inner portion of connector 300, e.g. thatis enclosed by a housing 318, etc. The housing 318 may preferably be aninjected molded plastic housing, but according to other embodiments maybe e.g., a cast aluminum housing, a composite housing, of a conventionalhousing material of a type known in the art, etc. Furthermore thehousing 318 may be configured in a way that prevents functionalityproblems in connector 300 e.g. electrical shorting, electricalisolation, system thermal irregularities, etc.

With continued reference to FIGS. 3A-3D, connector 300 may additionallyinclude shielding, e.g., backplanes, reference planes for signal qualitymeasures, etc., within the connector 300. Such shielding may furthermoreextend into a circuit board (embodiments with a circuit board shown inlater FIGS.) to which the connector 300 may be electrically coupled.

The second end 316 may also include an alignment feature 310 dividingthe second contacts 308 into multiple arrays. The multiple arrays maydivide contacts into the same and/or different size arrays of secondcontacts 308. Additionally, the multiple arrays may divide contacts ofdiffering size and/or contact type e.g., in order to separate datacontacts from power contacts, in order to separate differing datacontact types, in order to establish an easier pairing of the secondcontacts 308 with a pairing contact, etc. For example, in connector 300the alignment feature 310 divides the second contacts 308 into twoseparate arrays, each of which are of differing array sizes.

The alignment feature 310 may furthermore be configured to be receivedin a slot and/or indent of a card edge that is configured to be pairedwith the second end 316. For example, the alignment feature may bereceived in a slot and/or indent of a card edge that is paired with thesecond end 316, and may furthermore help to retain the card in thesecond end due to the alignment feature being substantially fit e.g.snuggly fit, abrasively fit, etc. within the slot and/or indent of acard edge.

According to other embodiments, the second end 316 may include a dividerthat divides the second contacts 308 into multiple identical arrays. Inanother embodiment, the divider may divide the second contacts 308 intomultiple differing arrays. In yet another embodiment, the divider maydivide the second contacts 308 into one or more differing arrays as wellas one or more identical arrays.

In another embodiment, the alignment feature 310 may include one or moredividers (not shown) that separate the second contacts 308 into arrayseach coupleable to a unique electronic device. The arrays separated bythe one or more dividers may be of different and/or the same size.Furthermore, the one or more contacts of each array may differ inconfiguration and/or have identical contact configurations. In oneexemplary approach, the connector may have two of the arrays of secondcontacts 308 like the array shown in FIG. 3A or another type, butstacked one atop the other, or side by side, for coupling with twounique electronic devices.

With continued reference to connector 300, the second end 316 includesan elongated slot 312 configured to receive the card edge of anelectronic device. According to various embodiments, the elongated slot312 may include an alignment portion, e.g., a partially angled portionwhich may assist in guiding the card edge of the electronic device asthe card edge of the electronic device is inserted, an insertionguidance rail, e.g. as the second contacts are coupled directly with thecard edge of an electronic device, etc., into the elongated slot 312,etc. Illustrative alignment portions are shown in FIG. 3B at the top andbottom of slot 312.

FIG. 3B is a front view of the connector 300. As shown in FIG. 3B,according to various embodiments the second contacts 308 may bepositioned along both sides, e.g., the right side and left side, of theelongated slot 312. However, in other approaches, the second contacts308 may be present along only a single side, or in any other arrangementas would become apparent to one skilled in the art upon reading thepresent disclosure. In further embodiments, the second contacts 308 maybe pins, e.g., similar to the first contacts 304 shown in the FIG. 3A.

FIG. 3C is a side view of the connector 300.

FIG. 3D is a bottom view of the connector 300. The first contacts 304 ofthe first end 314 are configured in two separate side by side arrayswhich may include signal and/or ground contacts. The configuration ofthe first contacts 304 of the first end 314 may furthermore varydepending on the spatial parameters of a component the connector 300 maybe electrically coupled to, e.g., a circuit board, an option board,etc., via contacts 304. Moreover, the first contacts 304 may be presentin a slot, e.g., similar to slot 312.

In a preferred embodiment, the connector has an aspect ratio of at least1:2 (width:height), more preferably at least 1:4, as measured along thefirst end, e.g., as shown in FIG. 3B and/or the second end, e.g., asshown in FIG. 3D.

FIGS. 4A-4C depicts a system 400 in accordance with one embodiment. Asan option, the present system 400 may be implemented in conjunction withfeatures from any other embodiment listed herein, such as thosedescribed with reference to the other FIGS. Of course, however, suchsystem 400 and others presented herein may be used in variousapplications and/or in permutations which may or may not be specificallydescribed in the illustrative embodiments listed herein. Further, thesystem 400 presented herein may be used in any desired environment.

System 400 includes a plurality of connectors 300. As previouslydescribed, various embodiments described herein may include one or aplurality of connectors 300 depending on the preferred embodiment, e.g.,two connectors 300, eight connectors 300 in system 400 for purposes ofthis example, twelve connectors 300, etc. In preferred approaches,system 400 may include a preferred range of 2-12 connectors 300, but mayvary depending on the preferred embodiment.

System 400 also includes a circuit board 402. According to variousembodiments, the circuit board 402 may be a motherboard, mainboard,backplane circuit board, printed circuit board (PCB), etc.

According to other embodiments, the circuit board 402 may be an optionboard cabled to a motherboard.

The circuit board 402 may further include conventional features, e.g.circuits, chips, etc., and in some cases having specialized contactarrays for coupling to the first contacts 304 of the connectors 300.

As previously described, the first end 314 of a connector 300 has aplurality of first contacts 304 coupled to the circuit board 402, e.g.,in a way that affixes the connector 300 to the circuit board 402,thereby establishing an electrical connection between the connector 300and the circuit board 402, etc.

Various embodiments of coupling the first contacts 304 to the circuitboard 402 will now be described below for purposes of an example.Further coupling embodiments may be alternatively and/or additionallyused to couple one or more connectors 300 and the circuit board 402.

According to various embodiments, the first contacts 304 may be coupledto the circuit board 402 by a solder tail coupling e.g. as shown insystem 400, etc. Solder tail coupling may be established between thefirst contacts 304 and the circuit board 402 by soldering, e.g., wavesoldering, a soldering of a type known in the art, etc., the firstcontacts 304 of connector 300 to drilled through holes in the circuitboard 402.

According to further embodiments, the first contacts 304 may be coupledto the circuit board 402 by a press fit coupling. Press fit coupling maybe established between the first contacts 304 and the circuit board 402by pressing oversized first contacts 304 of the first end 314 partiallyand/or fully into plated holes in the circuit board 402. Press fitcoupling may advantageously establish a reliable connection between theconnector 300 and the circuit board 402, e.g., by the press fittingestablishing an air tight seal between the connector 300 and the circuitboard 402, by using an oversized first contact that by design compressesas it is inserted into a plated hole of the circuit board 402, etc. Itshould be noted that the press fit coupling described herein may or maynot additionally include a soldering between the oversized firstcontacts 304 of the first end 314 and the plated holes in the circuitboard 402. Press fit coupling may furthermore eliminate reflection stubthat otherwise may reduce signal integrity or signal quality establishedby the coupling.

According to yet further embodiments, the first contacts 304 may becoupled to the circuit board 402 by a surface mount coupling (hereafterreferred to as “SMT”). According to various embodiments, SMT couplingmay be established between the first contacts 304 and the circuit board402 by pressing first contacts 304 into surface pads on circuit board402. The surface pads may include solder paste which may then may thencouple the first contacts 304 with the circuit board 402 once the solderpaste is melted e.g. via infrared reflow, via a heating of the solderpaste, via a soldering type known in the art, etc. The first contacts304 may furthermore be “L” shaped in order to establish an orthogonalcoupling between the second contacts 308 and the first contacts 304 (thefirst contacts 304 being coupled with the circuit board 402 at thesurface pads, etc.). SMT coupling may provide stronger signal integrityand/or performance, and therefore may be preferred.

According to one embodiment, the connectors 300 may be coupled to thecircuit board 402 on a recessed/lowered portion (not shown) of thecircuit board 402, so that the connector profile on the circuit board402 is low profile and/or flush with the surface of the circuit board402 to which the connector 300 is coupled.

It should be noted that in embodiments which include more than oneconnector 300 being coupled to the circuit board 402, the type ofcoupling may vary depending on the preferred embodiment. Alternativelyin embodiments which include more than one connector 300 being coupledto the circuit board 402, the type of coupling may be the same.

With continued reference to FIG. 4A, system 400 further may include afan (not shown) for inducing air flow across the connectors 300 in adirection 404 parallel to the first end 314. The connectors 300 mayfurthermore be spaced apart from one another in a direction orthogonalto direction 404 to promote cooling of system 400, e.g., in order tocool system 400 from heat that may be generated during system 400function, in order to prevent asperities (e.g. dust, etc.) from buildingup in system 400, etc. For example, closest facing portions of at leastsome of the connectors may be spaced apart by a distance sufficient toallow substantially uninhibited airflow therebetween in a directionparallel to the first end, e.g., the airflow between the adjacentconnectors is volumetrically reduced by less than 20%. Inducing air flowacross the connectors 300 in a direction 404 parallel to the first end314 may not otherwise be possible and/or as efficient in conventionalcard edge connection layouts with condensed vertical backplaneconnections.

FIG. 4B is a detailed side view of system 400 of FIG. 4A taken alongline 4B-4B. It should be noted that the connectors 300 of FIG. 4B areillustrated as being larger in size than the connectors 300 were in FIG.4A for the purposes of showing detail of the second end 316. It shouldbe further noted that the spatial configurations, e.g., the spacingbetween each of the connectors 300, the spacing between the outermostconnectors and the edge of the circuit board 402, etc., of connectors300 may vary depending on the preferred embodiment.

FIG. 4C is a detailed side view of system 400 of FIG. 4A-4B. It shouldbe noted that the spatial configurations, e.g., the portion ofconnectors 300 residing past the outermost edge of the circuit board402, the spacing between the connectors 300 and the edge of the circuitboard 402, etc., of connectors 300 may vary, e.g., connectors 300 mayalternatively be positioned flush with the outermost edge of the circuitboard 402, etc., depending on the preferred embodiment.

FIGS. 5A-5B depicts a system 500 in accordance with one embodiment. Asan option, the present system 500 may be implemented in conjunction withfeatures from any other embodiment listed herein, such as thosedescribed with reference to the other FIGS. Of course, however, suchsystem 500 and others presented herein may be used in variousapplications and/or in permutations which may or may not be specificallydescribed in the illustrative embodiments listed herein. Further, thesystem 500 presented herein may be used in any desired environment.

FIG. 5A is perspective view of the system 500. System 500 includesconnectors 300 and circuit board 402. System 500 further includes aplurality of electronic devices 502 each having a card edge 504 coupledto the second end 316 of a respective one of the connectors 300. Theelectronic devices 502 may be any type of electronic devices, e.g., suchas memory cards, data processing cards, electronic devices of a typeknown in the art, etc. Furthermore, each of the electronic devices 502of system 500 may differ from one another, e.g., differ in size, differin functionality, differ in how each card is coupled to the second end316 of a respective one of the connectors 300, etc. depending on theembodiment.

It should be noted that connectors 300 in system 500 are illustrated asbeing coupled to a single corresponding electronic device 502. In otherembodiments, more than one electronic device 502 may be coupled to oneor more of the connectors 300, e.g., when the connectors are designedaccordingly, when the circuit board is designed to accept such aconnector, etc.

The coupling between each of the card edges 504 of the plurality ofelectronic devices 502 and the respective connectors 300 may beuncoupled by various actions. For example, the coupling between each ofthe card edges 504 of the plurality of electronic devices 502 and therespective connectors 300 may be uncoupled. e.g., by a user and/oraccessor pulling out the electronic device 502 in a directionsubstantially similar to a direction in which the electronic devices 502are inserted for coupling with the first contacts 304.

As previously described in system 400, system 500 further may include afan (not shown) for inducing air flow across the connectors 300 in adirection 404. The connectors 300 and/or the electronic devices 502 mayfurthermore be spaced apart from one another in a direction orthogonalto direction 404 to promote cooling of system 500, e.g., in order tocool system 500 from heat that may be generated during system 500operation, in order to prevent asperities (e.g. dust, etc.) frombuilding up in system 500, etc.

Orthogonal card edge connection layouts described herein may maintainthe density of a card to board connection when the pitch between thecards is increased for cooling purposes. For example, when implementedin one or more spinning drive bays of a computer, this maintaineddensity may be especially appealing to consumer spatial demands. Thisbenefit may be not possible in conventional card edge connectionlayouts, e.g., vertical card edge connection layouts, etc.

FIG. 5B is a top down view of the electronic devices 502 attached to theconnectors 300 and the circuit board 402 of FIG. 5A taken along line5B-5B.

It should be noted that system 500 includes a plurality of eightconnectors 300 with eight corresponding electronic devices for examplepurposes. Further embodiments may include more or fewer connectors 300and/or electronic devices 502 of varying configurations. For example ina further embodiment, a circuit board may include sixteen connectors 300with only ten of the connectors 300 coupled to a correspondingelectronic device 502, e.g., where the remaining six uncoupledconnectors 300 may later be filled by a user when more flash memory isdesired, where the six uncoupled connectors and the ten coupledconnectors are staggered to provide more spatial spreading between theconnectors to further promote the cooling of system 500, etc.
